CLOSURE FOR CONTAINERS.

Application filed November 15, 1913.

To all whom it may concern Be it known that we, HENRY A. KEINEP. andEMILE PLANgoN, citizens of the United States, and'residents of the cityof New York, borough of'Queens, county of Queens, and State of New York,have invented certain' new and useful Improvements in Clo-- sures forContainers, of which the following is a specification.

This invention relates in general to closures for sheet-metal or othercontainers for liquids, with more particular reference to improvementsin the type of containers shown and described in a co-pendingapplication, filed Nov. 10, 1913, Serial No. 800,029, in which we haveset forth the most important features that should be possessed bycontainers of this character.

The principal objects of the present invention include the provision ofan improved closure for containers which shall possess to the highestpossible degree the necessary or desirable features or qualities setforth in the co-pending application referred to, and which in additionthereto shall be strong and durable, relatively light in weight, simpleand inexpensive, and shall preferably be of self-contained construction,thus avoiding multiplicity of separate parts and correspondinginterference with rapid handling, convenient packing and-storage andcommercial use of the closures.

Our invention will be more readily understood by reference to theaccompanying drawings, forming a part of this specification, in whichFigure 1 is a side elevation of the upper portion of a containerprovided with a clo sure embodying our invention, a portion of theclosure being shown intransverse vertical section taken on the centerline there of; Fig. 2 is a similar view with the entire closure andadjacent parts of the container shown in transverse vertical sectiontaken on the center line thereof; Fig. 3 is a top plan view of theclosure as applied to a container; Fig. 1 is a sectional detail showinga modification of the connection between two parts of the container, asdescribed hereinafter; Fig. 5 is a sectional] detail showing anothermodification of said con,- nection; Fig. 6 is a side elevation of aportion of the container, showing said lastnamed modification; Fig. 7 isa top plan view of a container, showing a third modifi- Specification ofLetters Patent.

cation of the connection between two parts of the container, and Fig. '8is a sectional detail of said third modification.

Referring now to the drawings in detail, in which similar referencenumerals indicate corresponding parts in the several views,

numeral 11 designates the body portion of a sheet-metal container of thecharacter to which we have reference, the upper portion 12 thereof beingdome-shaped or otherwise reduced in diameter as it extends upward,terminating in the neck 13 which is of suitable design and constructionto cooperate with the closure 14, as described hereinafter.

The complete closure comprises the cap or stopper member 15, thesecuring or looking member 16 and the packing or sealing member 17. Inour improved container the stopper member and the securing member areconnected in such a way that while provision is made for relativemovement between them, in the manner described hereinafter, they form ineffect a self-contained unit. Thepacking or sealing member 17 is notprimarily connected with either of the other members of the completeclosure, but is so designed and constructed as to cooperate therewith.

' The cap or stopper member 15 is preferably constructed either of lightcast metal or of pressed sheet-metal and is substantially bowl or panshaped with a flange 18 extending continuously around the outside ofsaid member and adapted to rest upon the upper edge of the neck 13, andwith a beaded or turned upper edge 19 which serves to reinforce the saidmember and maybe employed as part of the connection between the stoppermember and'the securing member.

The securing or looking member 16 consists of a'four-armed skeleton orframe, this member as shown preferablyv comprising multiple armsradiating from a common center and disposed at right angles to eachother, and either being all constructed of a single piece of metalorbeing made up of two or more separate pieces suitably connected at ornear their common center. Two of these arms,'20 20, which are preferablydiametrically opposed to each other, are intended to be employed in themanner described hereinafter for securing the said member to thecontainer, while the other two arms,,2121, are used to connect the saidstock or other suitable packing material, the

outer edge thereof being turned upwardly and then outwardly throughoutthe circumference of the disk, so that the said edge may be interposedbetween the flange 18 of the stopper member 15 and the upper edge of theneck 13 of the container, and thus when said stopper member is clampedfirmly in place a substantially hermetic seal is produced.

The arms 20 20, of the securing member 16 are turned downward at theirends and their extreme outer edges are then turned in to form hooks orjaws thereon, which are adapted to engage lugs 23 either formed as partof the neck of the container or suitably secured thereto. The contactsurfaces of the hooks or jaws 22 and the lugs 23 are slightly inclinedfrom the horizontal, so that as the hooks or jaws are introduced underthe lugs and advanced thereunder by turning the securing member 16slightly a wedging eifect is secured by the cooperation of the hooks oraws 22 and the lugs 23 and the stopper member 15 is secured tightly inplace and clamps the edge of the sealing member 17 between the flange 18of the stopper member 15 and the upper edge of the neck 13 of thecontainer. By revolving the locking member 16 slightly in a reversedirection, the pressure of flange 18 upon the edge of disk 17 isgradually reduced until the hooks or jaws 22 pass entirely out ofengagement with the lugs 23, when the combined stopper member andsecuring member maybe removed from the container, leaving the sealingmember loosely in place and readily removable.

1n the closure shown in Figs. 1, 2 and and in the three modificationsthereof shown in the other figures of the drawings, the securing member16 is not rigidly secured to the stopper member 15, but is so connectedtherewith as to permit at least partial revolution of the formerrelative to the latter. Thus in securing the closure in place byengaging the jaws or hooks 22 of the securing member 16 with the lugs 23on the neck of the container, the stopper member is not turned with thesecuring member 16, and hence there is no frictional motion between thestopper member 15 and the disk 17, such as would tend to abrade or cutthe said disk, particularly if it were in a moist condition.

The outer ends of the arms 21 21, of the securing member 16 are soshaped and di mensioned as to secure said sealing member loosely to thestopper member 15. As shown in Figs. 1, 2 and 3, the outer ends of thearms 21 21, are bent downward and then outward, so as to engage theinwardlyturned upper edge 19 of the stopper membeu 15. In themodification shown in Fig. 4 the outer ends of the arms 21 21, are bentto form hooks adapted to engage the outwardly-turned head 24: formed onthe upper edge of the stopper member 15. In the modification shown inFigs. 5 and 6 the outer ends of the arms 21 are turned downward and thenoutward and are so shaped and dimensioned as to engage slots 25 formedin the sides of the stopper member 15 immediately below the beaded upperedge thereof, said slots being of such length so as to permit sufiicientrotation of the securing member 16 to engage the hooks or jaws 22thereof with the lugs 23, and to release them from such engagement,without causing any rotation whatever of stopper member 15 in its seat.In this construction the extreme ends of the arms 21 are upset orotherwise spread after being introduced into the slots 25, so as toprevent disengagement of the arms from the slots. The modification shownin Figs. 7 and 8 difiers from that shown in Figs. 5 and 6 only in thatthe ends of the arms 21 21, are turned downward to engage slots 26 26,formed in the bottom of the stopper member 15. The constructions shownin the three modifications are adapted to operate in the same manner asthat shown in Figs. 1, 2 and 3, and they differ therefrom only indetails of the connections between the stopper member 15 and thesecuring member 16.

In Fig. 1., one of the lugs 23 is shown as being provided with securingor locking means 27, adapted to prevent disengagement of the hooks orjaws 22 from the lugs 2-3, such means consisting of the ordinarypadlockorthe like.

Many modifications of minor details of our improved closure forcontainers will doubtless readily suggest themselves to those skilled inthis-art, and we therefore do not desire to limit our invention to thespecific construction herein shown and described.
